PillarNeSt: Embracing Backbone Scaling and Pretraining for Pillar-based 3D Object Detection

🔥🔥| 解读1 | PillarNeSt微信解读2 | PillarNeSt微信解读2

PillarNeSt is a robust pillar-based 3D object detectors, which obtains 66.9%(SOTA without TTA/model ensemble) mAP and 71.6 % NDS on nuScenes benchmark.

Visualization Results

News

Our paper has been officially accepted by the journal IEEE Transactions on Intelligent Vehicles (TIV) in April 2024.

Preparation

• Environments

Python == 3.6
CUDA == 11.1
pytorch == 1.9.0
mmcls == 0.22.1
mmcv-full == 1.4.2
mmdet == 2.20.0
mmsegmentation == 0.20.2
mmdet3d == 0.18.1

• Data
  Follow the mmdet3d to process the nuScenes dataset.

• Weights

Model weights are available at Google Drive and BaiduWangpan(PW: 1111).

Main Results

Results on nuScenes val set. (15e + 5e means the last 5 epochs should be trained without GTsample)

Config	mAP	NDS	Schedule	weights	weights
